This BitMEX review examines the exchange’s current fee structure, product range, regulatory history, and practical positioning for traders in 2026. BitMEX was founded in 2014 by Arthur Hayes, Ben Delo, and Samuel Reed and was the first exchange to introduce the now-ubiquitous USDT perpetual futures contract model. At its peak in 2019–2020, BitMEX handled over $10 billion in daily derivatives volume and was the definitive global derivatives venue. Its subsequent legal challenges, regulatory withdrawal from the US market, and the rise of competing platforms significantly reduced its dominance.
In 2026, BitMEX operates as a focused derivatives platform with a cleaner regulatory posture and a genuine competitive edge for traders who specifically value maker rebates: the platform pays traders a -0.01% rebate on perpetual contract maker orders, meaning liquidity providers are paid rather than charged to execute. This is a meaningful feature for algorithmic and high-frequency traders who consistently add liquidity.
Key Takeaways
- Perpetual futures maker: -0.01% rebate — traders who add liquidity are paid, not charged.
- Perpetual futures taker: 0.075% — above most major competitors at base.
- Spot trading available at 0.10% flat for major pairs.
- BitMEX was the originator of the perpetual futures model and remains a technically sophisticated derivatives platform.
- BitMEX founders faced DOJ charges in 2021 (settled 2022); the exchange itself paid a $100M settlement with CFTC and FinCEN. Regulatory posture has since been substantially rebuilt.
- Not available to US users.
What Is BitMEX?
BitMEX (Bitcoin Mercantile Exchange) launched in 2014 and pioneered the perpetual swap contract — a derivative instrument that tracks the spot price of an underlying asset indefinitely without an expiry date, using a funding rate mechanism to keep the contract price anchored to spot. This innovation became the dominant derivatives format in crypto and is now offered across all major derivatives exchanges globally.
After the 2021–2022 legal and regulatory challenges that removed the exchange from the US market and changed its leadership, BitMEX has rebuilt under new management with a compliance focus. The platform now serves professional and algorithmic traders primarily, with a product range concentrated on BTC and ETH perpetual contracts, inverse contracts, and a growing spot market.

BitMEX Trading Fees
| Market Type | Maker Fee | Taker Fee | Notes |
|---|---|---|---|
| Perpetual Futures (crypto) | -0.01% (rebate) | 0.075% | Makers receive payment |
| Equity Perpetuals (from Apr 2026) | 0.05% | 0.05% | Updated April 2026 |
| Spot Trading | 0.10% | 0.10% | Standard rate |
The maker rebate on BitMEX crypto perpetuals is the defining feature for its target user: algorithmic traders and market makers who place limit orders and consistently add liquidity to the order book. A -0.01% rebate means a trader placing $1,000,000 in maker orders earns $100 rather than paying a fee. For high-frequency market makers, this compounds significantly across large volumes. The taker fee of 0.075% is, however, among the highest of any major derivatives exchange at standard tier, making BitMEX expensive for traders who primarily take liquidity.
Regulatory History
In October 2021, the US DOJ and CFTC charged BitMEX and its founders with operating an unregistered trading platform and wilful AML violations. The exchange’s co-founders Arthur Hayes, Ben Delo, Samuel Reed, and Gregory Dwyer all pleaded guilty or settled charges by 2022 and paid personal penalties. BitMEX itself settled with the CFTC and FinCEN for $100 million in August 2021. Arthur Hayes served a period of house arrest and returned to the crypto industry as an investor and commentator after completing his obligations.
Post-settlement, BitMEX has operated under new compliance management with a focus on KYC enforcement and geographic access restrictions. The platform is not available to US users and has withdrawn from additional restricted jurisdictions. While the settlement amounts were significant, they resolved the outstanding legal matters without requiring exchange closure or triggering user fund losses.
